Olympic gymnast Simone Biles' brother has been charged with murder in a shooting on New Year's Eve in Cleveland that left three people dead and two wounded.

Tevin Biles-Thomas, 24, of Cleveland, was arrested Thursday at Fort Stewart in Georgia in the Dec. 31 shooting at an Airbnb property, according to a joint statement from the Cleveland Division of Police and the Cuyahoga County Prosecutor’s Office.

The statement said an "uninvited group" entered the house and "an altercation ensued" with the invited guests that led to gunfire.

Delvante Johnson, 19, and Toshaun Banks, 21, were pronounced dead at the scene, and Devaughn Gibson, 23, was pronounced dead at a hospital.

Biles-Thomas is facing 15 charges, according to an indictment filed in Cuyahoga County Court.

He is charged with two counts of murder, one count of voluntary manslaughter and one count of felonious assault for each of the people he is accused of killing.

He is charged with two additional counts of felonious assault for allegedly injuring two other victims.

The indictment said Biles-Thomas "had a firearm on or about his person or under his control while committing the offense and displayed the firearm, brandished the firearm, indicated that he possessed the firearm, or used it to facilitate" crimes.

He also faces one count of perjury and is scheduled to be arraigned Sept. 13.

"The relentless persistence of Cleveland Police Homicide detectives helped secure an indictment in this case," O’Malley said in a statement. "It is through their hard work that we can begin to seek justice for these victims."

Biles-Thomas is on active duty with the Army, serving as a cannon crewmember assigned to the 3rd Infantry Division at Fort Stewart, according to a spokesman for the base. He has served in the Army since 2014 and was deployed to Korea in 2018 as part of a rotation.

The spokesman said Fort Stewart officials were aware of the allegations against Biles-Thomas.

Biles-Thomas is being held at Liberty County Jail in Hinesville, Georgia. An arraignment is set for Sept. 13 in Cleveland, although it is unknown when he may be extradited. It was not immediately clear Friday if Biles-Thomas has a lawyer.

Representatives for Simone Biles, 22, said they had no comment.

On Thursday night, the Olympian tweeted, "eating my feelings don’t talk to me," but it's unclear what she was referring to.
